MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB190610.75 (trigger No 581882394, 21h 49m 31.20s , +42d 25m 12.00s, R=1.21) errorbox  84 sec after trigger time at 2019-06-10 18:01:14 UT, with upper limit up to  15.8 mag. Observations started at twilight.  The observations began at zenit distance = 77 deg. The sun  altitude  is -11.0 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB190610.75 errorbox  2261 sec after trigger time at 2019-06-10 18:37:31 UT, with upper limit up to  14.9 mag. Observations started at twilight.  The observations began at zenit distance = 76 deg. The sun  altitude  is -10.8 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.
